鱼雷航向运动是一个三阶系统,对这个系统进行时间最优控制分析是有意义的。本文首先在鱼雷航向运动线性化方程[1]的基础上,列写出状态方程式,对方程进行变换、解耦[2],然后参考文献[3]、[4]进行快速控制分析,最后得到用状态反馈的鱼雷航向运动时间最优控制规律的解析结果,并用方框图表示出来。 分析结果表明,航向运动时间最优控制应是邦——邦式控制,最多转换二次,转换的时间取决运动的状态,快速控制器大约由十几个非线性部件、十几个乘法器和几个加法器、积分器组成。 分析还表明文献[3]提供的方法,对于分析三阶系统快速控制是有效的。 本文分析结果的计算机仿真和模拟试验以及它的工程实现有待进一步研究。
Torpedo heading is a third-order system, which makes sense for optimal control of the system over time. Based on the linear equation of the torpedo course [1], the paper formulates the equation of state, transforms and decouples the equation [2], and then makes rapid control analysis by reference [3] and [4] The result of the optimal control law of torpedo heading time with state feedback is shown in the block diagram. The analysis results show that the optimal control of heading time should be state-state control with up to twice conversion time depending on the state of motion. The fast controller consists of a dozen non-linear components, a dozen multipliers and Several adders, integrators. The analysis also shows that the method provided by [3] is effective for analyzing the rapid control of third-order system. The results of computer simulation and simulation experiments as well as its project to be further studied.
